Myliobatidae (Eagle and manta rays)
Etymology: Myliobatis: Greek, mylo = mill + Greek, + Greek, batis,-idos = a ray (Raja sp.) (Ref. 45335).
Eponymy: Dr Ronald Hamlyn-Harris (1874–1953) was an English-born entomologist. [...] (Ref. 128868), visit book page.
More on author: Ogilby.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; benthopelagic; depth range 200 - ? m (Ref. 6871). Deep-water; 17°S - 26°S
Eastern Indian Ocean and Western Central Pacific: known from single specimens from off Forestier Island, Western Australia and Cape Moreton, Queensland in Australia. Possibly not distinct from Myliobatis tobijei or Myliobatis aquila; all three species need to be critically compared to determine if they are different species (Ref. 9862).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 48.0 cm WD male/unsexed; (Ref. 6871)
Rare offshore species (Ref. 9862). Ovoviviparous (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00119 - 0.01269), b=3.08 (2.83 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (83 of 100).
